• Find paths between two nodes using SQL sort by cost

  Hi gurus,
  
  I want to find all paths from the source node to the target node that will be sorted by the cost. I don't know if it was possible with the SQL statement. How to start with this query? The script to create the tables and data are given below:
  
  ------------------------------------------------------------------------------------------------------------------
  create table of nodes (nodeId int Primary Key, nodeName varchar (50));
  
  create paths of table (pathId int Primary Key, int fromNodeId, int toNodeId, int cost);
  
  insert into a values (1, 'ISL') nodes;
  insert into a values (2, "LHR") nodes;
  insert into a values (3, 'HYD') nodes;
  insert into a values (4, 'FLS') nodes;
  insert into a values (5, 'MUL') nodes;
  insert into a values (6, "KHI") nodes;
  insert into a values (7, 'QT') nodes;
  
  insert into values of paths (1,1,3,20);
  insert into values of paths (2,1,5,10);
  insert into values of paths (3,1,7,80);
  insert into values of paths (4,2,4,10);
  insert into values of paths (5,3,4,40);
  insert into values of paths (6,3,5,20);
  insert into values of paths (7,3,6,10);
  insert into values of paths (8,6,7,30);
  insert into values of paths (9,6,5,30);
  insert into values of paths (10,6,3,10);
  insert into values of paths (11,7,2,20);
  insert into values of paths (12,5,4,40);
  insert into values of paths (13,5,7,40);
  
  ----------------------------------------------------------------------------------------------------------------------------------
  Assume that the source = ISL and QT= target, there are different paths to QT ISL:
  
  Path relative cost DSB #.
  ==== ================================= =================
  1 ISL-> Multimedia-> QT 50
  2 ISL->->-> QT 60 KHI HYD
  3 ISL-> QT 80
  4 ISL-> HYD-> Multimedia-> QT 80
  5 ISL-> HYD at KHI-> Multimedia-> QT 100
  
  This gives us all possible paths, sorted by price.
  
  No indication or help will be appreciated.
  
  Thanks in advance and best regards

• two node Oracle RAC with two Oracle databases completely different on each node?

  We currently have two different applications that use Oracle databases.  Current configuration is two different oracle homes dbhome_1, dbhome2 with separate mounting LINUX points containing the Oracle homes and *.dbf files on a single host server.

  Previously, the idea was to set up a second server identical host configured as a 'data guard' for both of these databases.  Now, management wants to implement a cluster of CARS of two nodes, with each node running two databases.  With the Standard edition.

  I only did CARS of high availability and scalability for a single database.  Is it possible to run two completely different databases Oracle on a two-node RAC cluster?  I am inclined to think that they it has divided into

  two clusters RAC to two nodes on four small servers host.  Any suggestions or comments would be appreciated?

  Is it possible to run two completely different databases Oracle on a two-node RAC cluster?

  The short answer is Yes... it is possible.  It will work without any problem, as long as you have the resources available to an additional database.

  I am inclined to think that they it has divided into two clusters RAC to two nodes on four small servers host.

  There is another option.  In the past I have two databases on a RAC cluster that has been implemented for reasons of cost of license / (I don't think that this applies to itself, but you will need to check).

  However having seen on separate hosts that you have only potentially interruptions of service on a database if you decide to do something like upgrading from one of the databases and thus upgrade the GI as well.  This would mean interruptions in service for all your databases using the GI.

• Replication Failover clustering & Hyper-v on a two-node cluster

  Hello

  We have two identical servers.  One to use as a main server, which houses two virtual machines.  The other should be used as a back up in case the main server is not somehow.  We planned on using a solution of third-party software to back up our virtual machines and launch them in the event of failure of the principal server.  However, we discovered just gave the failover clustering in Windows Server R2 2012.

  We have tried to set up a cluster 2 nodes, with our virtual machines properly replicated to the backup server.  Excited by the present, we tried then to simulate failure of the primary server (by pulling on the cable network).  We were a little disappointed to find that the backup server is not automatically run virtual machines.  We did a survey and read than a solution of two nodes requires storage space for additional network (in addition to our two servers).

  I wonder if that's okay?  In other words, a two-node failover cluster requires separate network storage space.  If this is not correct, can someone point me to a set of instructions to correctly configure a two-node failover cluster that will automatically launch the virtual machines on the server backup (in the case of a failure of the principal server).

  Thank you

• two nodes ASM has the same instance name

  Hello

  I created a grid of ASM of two nodes, when the grid facility (11.2.0.1) finish he created the + ASM1 as instance name for my two knots.

  I have install the ORACLE_SID in + ASM1 and + ASM2 node1 and node2, respectively prior to installation.

  What is wrong, I do it for the installation of the grid? Please suggest.

  Thank you

  To create a virtual environment of RAC in VirtualBox or to share devices in an environment of ASM, you should turn off the virtual machine and change devices in VirtualBox using the following command:

  $ VBoxManage modifyhd asmdisk1.vdi - shareable type

  Then you can add the same features and use the disgroups on different nodes of the DSO. BTW, this is rather a question of the use of VirtualBox for which there is a special forum.

• Connectivity between two nodes of Virtual Box

  For a few days, I try to establish the network connectivity between two nodes OEL (Oracle Enterprise Linux) in Oracle Virtualbox. I tried everything I have found Google, but still nothing works, everytime I try to ping from one node to another node Hostname/IP is showing unknown host. All the advice everyone here will be great for me.
  
  Published by: 918868 on October 30, 2012 02:30

  When you create a virtual machine, by default VirtualBox allows virtual network card and selects the "Network Address Translation" (NAT) mode for it. In this way the guest can connect to the outside world using the networking of the host and the outside world can connect to services on the feedback that you choose to make visible outside of the virtual machine.

  This default configuration is good probably 95% of users of VirtualBox. VirtualBox is, however, extremely flexible in how it can virtualize networks. It supports multiple virtual NICs per virtual machine, the first four that can be configured in detail in the Manager window. Additional network cards can be configured on the command-line with VBoxManage.

• Cluster of P2V existing Windows 2003 two nodes exchange 2007

  Hello

  I want to know how I can create a cluster of the P2v of my production windows node cluster on a host two unique esx4i. It is only for purposes of laboratory and test. The reason why I've done a P2v is I want to imitate my production environment, and as production data.

  I've done a p2v of my node Exchange 2007 cluster two production Windows 2003 64-bit.  How can I reconfigure disks (quorum, data) for the cluster?

  I've seen a lot of e of documents telling me to remove the discs and re create, but I want to keep the data.

  I would like to know if someone has done with success the P2v cluster.

  Please notify.

  I understand you want to keep the data - this guide will give you necessary for nodes in vm configurations and storage relavent - if you want to keep the two nodes in the cluster on separate from ESX boxes, then you will need to maintain a quorum and the shared data on the physical SAN LUNS and allows to connect to storage RDM - if they all exist on the same ESX Server I shute evrything down - P@V primary node with the disk data and shared quorum, then P2V system disk of secondary nodes - in both cases follow the configurations described in the guides and you should be good to go-

• determine if the camera is a camera or two nodes

  Hello world

  is there a way to determine via scripts, if a camera is a camera of a node or a camera of two nodes?

  I tried to check if

  Camera.Property ("ADBE Transform Group"). Property ("Point of Interest")

  is defined, but it doesn't seem to exist also for the cameras of a node that is not a point of interest.

  Best,

  Mathias

  You must use a workaround to check if properties are active. It's the one I use generally:

  activeItem var = app.project.activeItem;

  var cam = activeItem.layer (1);

  var anchProp = cam.property("ADBE_Transform_Group").property ("ADBE Anchor Point");

  point of interest is the anchor.

  var propVisible = true;

  try {}

  anchProp.selected = true;

  } catch (e) {}

  propVisible = false;

  }

  If (propVisible) anchProp.selected = false;

  Alert ("visible property =" + propVisible);

• Need the XQuery function that compares two nodes.

  Is there a any function XQuery for the OSB 10 g which compares two nodes with a correct management of redundant namespaces?
  There is a function "" fn:deep - equality "that compares two nodes." But it fails when one node is to have redundant namespaces as an attribute.
  I need a XQuery function that compares two nodes for the same content, same child nodes and their content, the same attributes of the child nodes except the attribute xmlns for one of the node that has redundant namespaces (namespace that are already defined in the parent nodes or any unnecessary space of names).
  
  for example, it should treat following two equal nodes:
  
  < has t '1' = >
  < xmlns:ns1 b = "ns1" >
  2
  < /b >
  < /a >
  
  
  < has t '1' = >
  < b >
  2
  < /b >
  < /a >
  
  
  Above two nodes are the same attributes and content except 1st node attribute xmlns. Wise business scenario it is redundant but not bad, same case can occur and I need to take care of these scenarios.
  Please let me know about a feature or logic to treat this

  in fact the XMLs 2 you posted are different to a '2 '.

  I tried this:

  XQuery version "1.0" encoding "Cp1252";
  (: pragma type = "xs: anyType" ::))

  declare namespace xf = "http://tempuri.org/OSB%20Project%201/compare/";

  declare function:compare() xf
  {element (*)}

  Let $a: = (t = '3')(b xmlns:ns="ns") 2 (/ b) (/a)
  Let $b: = (a t = "3") (b) 2 / (b) (/a)

  return {fn:deep - equal ($a, $b)}
  };

  XF:Compare()

  and it does not work as expected, it is the additional xmlns:ns = 'ns' are ignored...

  I had a similar problem, but in the end, I couldn't figure how to remove the white lines.

  I have given up trying to remove the white and just changed the color of the treeview and everything that was drawn on the top in white.

  It was the only way I managed to hide lines.

  Thank you

  Steve,

  XQuery can help in this case:

  SELECT x.*
  FROM temp
     , XMLTABLE('for $begin in /document/body/paragraph/run[fld/@type="begin"]
                 let $end := $begin/following-sibling::run[fld/@type="end"][1]
                 return $begin/following-sibling::run[. << $end]'
         PASSING temp.xml_template
         COLUMNS res varchar2(100) PATH 'text'
       ) x  ;
  

  Explanation:

  This FLWOR expression traverses all nodes 'start' in the document, finds the corresponding node of the 'end' and returns the sequence of "run" nodes follows 'begin' and above 'end '.

  If you want to concatenate all the fragments of text in a block, you can also do it directly, like this:

  for $begin in /document/body/paragraph/run[fld/@type="begin"]
  let $end := $begin/following-sibling::run[fld/@type="end"][1]
  return string-join($begin/following-sibling::run[. << $end]/text, "")

• Restoration of the CARS (two nodes) DB DB to single node

  Hi guys,.

  Environment:

  DB on RAC (2 knots)

  Operating system Windows 2008R2

  Oracle 11 g 2

  Backup: EMC Networker.

  Requirements:

  Need to restore to this DB on another machine (a node), for testing and the update of the end.

  Question:

  Recovery is not successful, but restoration of Controlfiles and data files was done successfully for the new machine with new directory structures.

  Error:

  ORA-10879: error reported in parallel recovery slave

  ORA-01547: WARNING: RECOVER succeeded but OPEN RESETLOGS would get below error

  ORA-01152: 1 no file has been restored from a sufficiently old backup

  ORA-01110: data file 1: ' D:\APP\DATA\SYSTEM01. DBF'

  Now wants to open the DB after recovery, how can I do this? (need a scripts...)

  FYI, the Scripts using #.

  --------------------

  run

  {

  ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE '.

  parms 'ENV = (NSR_SERVER = bkpsrv, NSR_CLIENT = dbsrv)';

  ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE '.

  SET NEWNAME for DATAFILE '+ DBDATA/undotbs2.264.777378113' to 'D:\app\data\undotbs02.dbf ';

  until the 16510 sequence;

  restore the database;

  recover the database;

  OUTPUT CHANNEL ch00;

  Ch01 CHANNEL;

  }

  ---------------------------------------------------------

  Yes, for CARS, the SET clause until is the SEQUENCE until the VALUE n WIRE m

  For example, if you specified the VALUE up to this WHAT SEQUENCE 16510 THREAD 2, you must also all him up ArchiveLogs WIRE 1 to the same point in time as THREAD 1 16510.   Oracle needs * two * discussions to be able to RECOVER the database because the transactions take place in the two threads.

  The _allow_resetlogs_corruption is a choice of LAST OPTION only if the Support of Oracle indicates you that you have no other options.  It can result in an inconsistent database - for example an uncomitted transaction may appear as committed because the restore information not applied OR a transaction that has been committed by users not be applied because that do it again because it is ignored.

• Cannot configure a two-node MSCS cluster.

  Server configuration iSCSI by Starwind 5.4 on Win7 and Win two, 2003 virtual machines as nodes in cluster on vSphere 4.0. Using Starwind how to configure the Quorum and another disk shared between 2 virtual machines. The path that is on each virtual machine by the Microsoft iSCSI initiator to get both drives shared directly from iSCSI Server (win 7).  When configure a cluster on a node, download info on photo 1, check the yellow error, got the image 2. At the end of the installation, download the info from the error: the network path is not found (photo 3), check the logs of the Win system, download the info on photo 4. Before and after her, with check the 3 NICs IP network and ping them, all of them are good. After putting new IP Address/subnet mask on the network cards that are for the beats, the problem is still there.

  I'm confused what is wrong. Is it a problem that the pulse line connects via a vSwitch without physical NETWORK card as Microsoft says heart rate must be connected directly?

  I don't think it would be a network ESX problem since all your NETWORK cards are online and respond to pings.   I am curious about your first screen printing where the cluster cannot be brought online due to the INVESTIGATION period is already on the network.   Is it possible that the IP address is in use elsewhere on the network?

  I'll move this thread to the VM forum and the guest operating system to see if anyone can help troubleshoot the configuration of comments.
